Initially, I had problem with streaming sound along with video. Adding, `:input-slave=alsa:// :v4l2-standard=1` solved this. You can try another values for `:v4l2-standard` ie. 0, 1 or 2, depending which microphone you want to use.

Above command will stream HD video (1280×720) in .ogg format (natively suported by most browsers) @ ~2Mbps (2000kbps). If you have slower connection, you can change `vb=2000` to `vb=1000` (~1Mbps) and play with lower resolutions. You can check available resolutions of your camera by:

lsusb -v | egrep -B10 'Width|Height'

This stream, however, is available to everyone. To limit it only to localhost, you can use iptables:
